Description

General description

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards

Application

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Biochem/physiol Actions

Salsalate is a nonsteroidal anti-inflammatory drug (NSAID), a nonacetylated salicylate with no more problems of gastrointestinal bleeding than placebo. It inhibits synthesis and release of prostaglandins through the inactivation of cyclooxygenase-1 (COX-1) and COX-2. Salsalate is currently being investigated as a treatment for Type 2 diabetes with possible use to prevent the disease in people at risk. It reduces blood glucose concentrations in patients with type 2 diabetes, as well as in insulin-resistant patients without diabetes.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
